Hi.
I suggest change event flow.
The PanRecognizer have "pan(start|move|end|cancel)" and "pan(left|right|up|down)" event. The PinchRecognizer have "pinch(start|move|end|cancel)" and "pinch(in|out)" event.
The "emit" method of Recognizer is fire "pan(start|move|end|cancel)", "pinch(start|move|end|cancel)".The "emit" method of Manager is fire "pan(left|right|up|down)", "pinch(in|out)" .
The "emit" method of PanRecognizer call step is
1. Manager#emit call
2. Recognizer#emit call
So. The event flow of PanRecognizer is "pan(left|right|up|down) -> panstart -> (left|right|up|down) ....-> panend".
The "emit" method of PinchRecognizer call step is
1. Recognizer#emit call
2. Manager#emit call
So. The event flow of PinchRecognizer is "pinchstart -> pinch(in|out) .... -> pinchend -> pinch(in|out)".
Event flow is different from each other. [sample]
I suggest that same event flow.
